# Interactive video lesson plan for: What are rational numbers? Lesson for 7th grade math (part 1)

#### Activity overview:

Rational numbers are numbers that can be written as a RATIO of two integers. In this lesson, we look at various examples of rational numbers.

First, we see that ALL fractions and whole numbers are obviously rational numbers. What about decimals?

We write various decimals as fractions and see that they, also, are rational. I also show one example of a non-ending repeating decimal. (There are more in 2nd part of this lesson.)

Lastly for this 1st part, we take a quick look at negative fractions. I show how they also are rational numbers, and how to simplify them.

The 2nd part of the lesson is at https://youtu.be/e7JX4Rjk44g
